From a6a843196869659ee55238e474be29018987c4bf Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Wed, 7 Jan 2015 19:23:15 -0800 Subject: [PATCH] receive-pack.c: shorten the execute_commands loop over all commands Make the main "execute_commands" loop in receive-pack easier to read by splitting out some steps into helper functions. The new helper 'should_process_cmd' checks if a ref update is unnecessary, whether due to an error having occurred or for another reason. The helper 'warn_if_skipped_connectivity_check' warns if we have forgotten to run a connectivity check on a ref which is shallow for the client which would be a bug. This will help us to duplicate less code in a later patch when we make a second copy of the "execute_commands" loop. No functional change intended.
